Designing for Cisco Internetwork Solutions (DESGN, legacy) — Question 33

Your company's Cisco routers are operating with EIGRP. You need to join networks with an acquisition's heterogeneous routers at 3 sites, operating with EIGRP and OSPF. Which describes the best practice for routing protocol deployment?

Answer options

• A. Apply OSPF throughout both networks
• B. Apply one-way redistribution exclusively at each location
• C. Apply two-way redistribution exclusively at each location
• D. Apply two-way redistribution at each location with a route filter at only one location
• E. Apply two-way redistribution at each location with a route filter at each location
• F. Apply EIGRP with the same autonomous system throughout both networks E

Correct answer:

Explanation

The correct choice is F, as using EIGRP with the same autonomous system provides a seamless integration of both networks, allowing for efficient routing. Options A and C do not accommodate the existing EIGRP setup properly, while B only allows for limited communication. Option D imposes unnecessary complexity with a route filter and may hinder necessary routing information exchange. Option E complicates the setup further with multiple route filters.
